Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 9 kA at 690 V — the 415 V figure is the one that matters for most European industrial panels; it tells you this breaker can clear a bolted fault at the main distribution board without upstream fuses needing to blow. Current derates with ambient temperature: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, 450 A at 70 °C. The depth (110 mm) is the dimension that matters for shallow backpanels; check your enclosure depth against that figure before committing the BOM. Supplied with three auxiliary switches (HQ type) as standard, and no undervoltage or shunt release fitted — if your safety circuit requires a UVR, you'll need to add one; the basic switch variant is 3VA2463-5JQ32-0AA0. Communication function is built in (Ethernet or fieldbus via the SENTRON communication module) — useful for energy monitoring and remote trip indication without extra wiring.","metaTitle":"Siemens 3VA2463-5JQ32-0AD0 SENTRON MCCB, 630 A, 3-pole","metaDescription":"Siemens SENTRON 3VA2463-5JQ32-0AD0 molded case circuit breaker, 630 A, 3-pole, 110 mm depth, 138 mm width, 248 mm height.
